核心提示： “鋰電池放電放得越盡，電池的損耗就會越大，”艾克郎大學，幫助美國太空總署NASA研究延長電池壽命的電子工程教授Tom Hartley，說到，“給電池充電充得越滿，電池的損耗也會越大。鋰電池最好是處于電量的中間狀態，那樣的話電池壽命最長。”
　　淺談鋰電(dian)池放電(dian)的誤(wu)區

　　“鋰電(dian)池(chi)(chi)放(fang)電(dian)放(fang)得(de)(de)越(yue)盡，電(dian)池(chi)(chi)的損(sun)耗就(jiu)會越(yue)大，”艾克郎(lang)大學(xue)，幫助(zhu)美國(guo)太空總署NASA研究延長(chang)電(dian)池(chi)(chi)壽命(ming)的電(dian)子(zi)工程教授Tom Hartley，說到，“給電(dian)池(chi)(chi)充電(dian)充得(de)(de)越(yue)滿，電(dian)池(chi)(chi)的損(sun)耗也會越(yue)大。鋰電(dian)池(chi)(chi)最好是處于電(dian)量(liang)的中間狀態，那樣的話電(dian)池(chi)(chi)壽命(ming)最長(chang)。”

　　首先(xian)，過高(gao)和過低的(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)量(liang)狀態對(dui)鋰(li)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)的(de)(de)壽(shou)(shou)命(ming)(ming)有最(zui)不利(li)的(de)(de)影響(xiang)，而(er)充(chong)放(fang)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)循環次(ci)數(shu)反(fan)而(er)是次(ci)要 的(de)(de)。其實，大多數(shu)售賣電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)器或(huo)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)上(shang)標識的(de)(de)可反(fan)復充(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)次(ci)數(shu)，都是以放(fang)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)百(bai)分(fen)之80為基準測試得(de)出的(de)(de)。實驗表明，對(dui)于一些筆記本電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)腦的(de)(de)鋰(li)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)，經常讓電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya) 超過標準電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)0.1伏(fu)(fu)特，即(ji)從4.1伏(fu)(fu)上(shang)升到(dao)4.2伏(fu)(fu)，那么電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)的(de)(de)壽(shou)(shou)命(ming)(ming)會(hui)減半，再提高(gao)0.1伏(fu)(fu)，則壽(shou)(shou)命(ming)(ming)減為原來(lai)(lai)的(de)(de)3分(fen)之一;長期低電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)量(liang)或(huo)者無電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)量(liang)的(de)(de)狀態則 會(hui)使電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)內(nei)部對(dui)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)子移動的(de)(de)阻(zu)力越來(lai)(lai)越大，于是導致電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)容(rong)量(liang)變(bian)小。美國宇航局NASA讓其哈勃(bo)太(tai)空(kong)望遠鏡上(shang)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)的(de)(de)消耗電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)量(liang)設(she)定在總容(rong)量(liang)的(de)(de)百(bai)分(fen)之10，以確保 電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)可以反(fan)復充(chong)放(fang)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)10萬次(ci)而(er)不必(bi)更(geng)新。

　　其次，溫度對鋰電(dian)(dian)(dian)(dian)池(chi)壽命(ming)也有較(jiao)大的(de)(de)影(ying)響(手機和其他小(xiao)型電(dian)(dian)(dian)(dian)子(zi)設備(bei)對此點可忽略)。冰點以下的(de)(de)環(huan)境有可能使鋰電(dian)(dian)(dian)(dian)池(chi)在電(dian)(dian)(dian)(dian)子(zi)產(chan)品打(da)開的(de)(de)瞬間燒毀，而過熱的(de)(de) 環(huan)境則(ze)會縮減電(dian)(dian)(dian)(dian)池(chi)的(de)(de)容量。因此，如果(guo)筆電(dian)(dian)(dian)(dian)長期使用(yong)外接電(dian)(dian)(dian)(dian)源也不(bu)將電(dian)(dian)(dian)(dian)池(chi)取下來，電(dian)(dian)(dian)(dian)池(chi)就長期處于筆記(ji)本排出的(de)(de)高(gao)熱當(dang)中，更主要的(de)(de)是，電(dian)(dian)(dian)(dian)池(chi)長期處于百分之100 的(de)(de)電(dian)(dian)(dian)(dian)量狀態，很快就會報廢(fei)。

　　由以(yi)上，我(wo)們可(ke)以(yi)總結出以(yi)下幾(ji)點確(que)保鋰電池容(rong)量和壽命的注意事項：

　　目前大多數電子產品的(de)電池(chi)都(dou)采(cai)用鋰電池(chi)，鋰離(li)子電池(chi)自(zi)1990年問世以(yi)來，因其卓越(yue)的(de)性(xing)能得(de)到了迅猛的(de)發(fa)展，并廣泛地(di)應用于社會，鋰電池(chi)生產商也因此得(de)到了最大規模(mo)的(de)發(fa)展。不(bu)需要將鋰電池(chi)充(chong)到百分(fen)之100滿(man)電，更(geng)不(bu)要將電量使用殆盡(jin)。在情(qing)況(kuang)允許(xu)的(de)情(qing)況(kuang)下，盡(jin)量使電池(chi)的(de)電量維持在半滿(man)狀態(tai)附近，充(chong)電與放電的(de)幅度越(yue)小越(yue)好;

　　通用(yong)Chevy Volt電(dian)動車(che)的(de)出廠(chang)設計就(jiu)是強制將電(dian)池(chi)電(dian)量維(wei)持在20%至80%，而蘋(pin)果(guo)筆電(dian)的(de)內置電(dian)池(chi)可(ke)能也是運用(yong)了(le)這(zhe)一方法(包括其他一些筆電(dian)和(he)電(dian)子(zi)產(chan)品)，讓電(dian)池(chi)的(de)可(ke)充放電(dian)周期(qi)數(shu)增加。

　　不要將鋰電池(尤其是筆記本鋰電池)長期在設備使用外接電源、充電器的(de)情(qing)況(kuang)下工(gong)作(zuo)。就算您的(de)筆記本散熱良好，長期(qi)百分之100的(de)電(dian)量就等于對鋰(li)電(dian)池(chi)的(de)謀殺。

　　1. 如果你長期用外接電(dian)(dian)(dian)(dian)(dian)源為筆記本(ben)電(dian)(dian)(dian)(dian)(dian)腦供電(dian)(dian)(dian)(dian)(dian)，或者電(dian)(dian)(dian)(dian)(dian)池(chi)電(dian)(dian)(dian)(dian)(dian)量(liang)(liang)已(yi)經超過80%，馬上(shang)(shang)取下你筆記本(ben)的(de)電(dian)(dian)(dian)(dian)(dian)池(chi)、平(ping)(ping)時充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)不(bu)需將(jiang)電(dian)(dian)(dian)(dian)(dian)池(chi)充(chong)(chong)滿，充(chong)(chong)至(zhi)80%左右即可(ke);調整操作系統的(de)電(dian)(dian)(dian)(dian)(dian)源選項，將(jiang)電(dian)(dian)(dian)(dian)(dian)量(liang)(liang)警報調至(zhi)20%以(yi)上(shang)(shang)，平(ping)(ping)時電(dian)(dian)(dian)(dian)(dian)池(chi)電(dian)(dian)(dian)(dian)(dian)量(liang)(liang)最(zui)低(di)不(bu)要低(di)于20%，在下降到20%以(yi)前即要進(jin)行充(chong)(chong)電(dian)(dian)(dian)(dian)(dian);

　　2. 手機等小(xiao)型(xing)電(dian)(dian)(dian)子設備，充(chong)好(hao)電(dian)(dian)(dian)了就應(ying)立刻斷開電(dian)(dian)(dian)源線(xian)(包括充(chong)電(dian)(dian)(dian)功能的USB接(jie)口(kou))，一直接(jie)著會損害電(dian)(dian)(dian)池(chi);要(yao)經常充(chong)電(dian)(dian)(dian)，記起來就充(chong)，但不必非(fei)得把電(dian)(dian)(dian)池(chi)充(chong)滿;

　　3. 無論是對筆記本還(huan)是手機等，都(dou)一定不要讓電池耗(hao)盡;

　　4. 如果要外出旅行，用電池充電器充(chong)(chong)滿吧，但請記得在條件允許的情況下隨時(shi)為電器充(chong)(chong)電，為了電池(chi)壽(shou)命(ming)，一定不要等到電池(chi)放干。
